Title: Automatic chemistry analyzer
Inventor: GOODALE DAVID L
IPC: G01N35/02
Filed: 1997-06-30
Abstract: An automatic chemistry analyzer is provided having a high throughput and a high reliability. The analyzer uses nephelometric and turbimetric analyzers (68) to analyze a wide variety of parameters within liquid samples typically generated in, for example, a large medical testing laboratory. The machine employs a unique probe (84) and stirring rod (86) assembly (80) mounted at a slight angle (.alpha.) with one another using rack and pinion assemblies (106) so that the lower end of the probe (84) and the lower end of the stirring rod (86) are in very close proximity to one another. This feature allows the machine to be used in unusually small reaction cuvettes (54). The analysis machine also includes an onboard control sample (78) so that the machine can be programmed to periodically calibrate its analyzing equipment during the course of normal operation. The machine also includes a sample station carousel (24) having retainer clips (39) for retaining a sample container rack (30) which is constructed to retain a bar-coded card (37) containing information regarding reagents used in the machine. A bar code reader (47) located proximate to the sample carousel reads the bar-coded reagent information into the controller.      Also provided are a cuvette wash station (130) and a waste trap assembly (138).

Title: Crawler web for crawler chains
Inventor: HALL HANS
IPC: B62D55/27
Filed: 1998-12-11
Abstract: A crawler web for crawler chains of crawler vehicles, in particular for ski slope vehicles or cross-country trackers, is proposed, which is fastened, transversely to the running direction, to mutually parallel bands oriented in the direction of travel and which comprises an elongated basic body which has a sheet-like support in the direction of the bands. The invention provides a crawler web which can be adapted individually for different applications and can be produced at comparatively low cost. This is achieved in that the basic body comprises, in cross section, two side legs with a connecting web arranged between them, at least one side leg approaching the other in such a way that a cutting edge can be inserted between the legs.

Title: Transmission of digital signals by orthogonal frequency division multiplexing
Inventor: VIJAYAN RAJIV
IPC: H04N21/2315
Filed: 1998-06-16
Abstract: In an orthogonal frequency division multiplexing (OFDM) system (10) which uses an outer Reed-Solomon encoder and interleaver (24) and an inner convolutional encoder (26), after the inner convolutional encoding the data bits are interleaved by an inner interleaver (28), and then grouped into symbols, each symbol having "m" bits.  After grouping, the symbols are mapped to a complex plane using quadrature amplitude modulation (QAM). Thus, bits, not symbols, are interleaved by the inner interleaver (28). A receiver (12) performs a soft decision regarding the value of each bit in each complex QAM symbol received.
